266 DRIVING AND OPERATING
{Warning
To prevent serious injury or death,
be alert and pay special attention
when passing highway exits,
entrances, and crossings with Super
Cruise, and be ready to take control
of the vehicle when necessary.
Changes in lane markings around
exits and entrances can
momentarily cause Super Cruise to
not detect the correct lane. If this
occurs, Super Cruise may attempt
steering inputs to bring the vehicle
back into the correct lane and, in
rare circumstances, could
over-correct and cause the vehicle
to momentarily cross into a lane
next to your vehicle unless you
manually steer to maintain your
lane position.The Driver Attention System (DAS) on
the steering column continually
monitors driver head and eye position
to estimate driver attention to the
road. The camera does not record or
share pictures, audio, or video.
Sunglasses, hats, or other types of
clothing that change the shape of the
head may interfere with camera
performance. To improve camera
performance, raise or lower the
steering wheel, or change the seat
position.
Pay close attention to the road ahead
to avoid these three increasing alerts:

268 DRIVING AND OPERATING
Stationary or Very Slow-Moving
Objects; Cross-Traffic
{Warning
Super Cruise is not a crash
avoidance system and will not steer
or brake to avoid a crash. Super
Cruise does not steer to prevent a
crash with stopped or slow-moving
vehicles. You must supervise the
driving task and may need to steer
and brake to prevent a crash,
especially in stop-and-go traffic or
when a vehicle suddenly enters
your lane. Always pay attention
when using Super Cruise. Failure to
do so could result in a crash
involving serious injury or death.
Curves in the Road
{Warning
The vehicle could drift out of your
lane of travel. To prevent crashes,
always be ready to manually steer. (Continued)
Warning (Continued)
Super Cruise may not detect your
lane on curves in the road. Super
Cruise may not detect the markings
that show your lane. You may not
have time to react to a vehicle in
the lane next to your vehicle while
on curves in the road.
Super Cruise may operate differently
in sharp curves. It may drift out of
your lane of travel if the curve is too
sharp.
When entering a curve, Super Cruise
may not detect the lane markings and
may not adjust the steering enough to
stay in your lane of travel. When this
happens, you will need to steer the
vehicle.
Super Cruise may detect other lane
markings that are not in your lane
and may or may not steer
appropriately to maintain your lane.
Super Cruise may occasionally provide
an alert and/or steering that is
considered unnecessary. It could
respond to lane markings in different
lanes, signs, guardrails, and other
stationary objects when entering or

Park Assist
The vehicle may be equipped with the
Rear Park Assist (RPA) and Front Park
Assist (FPA). The Park Assist system
may provide assistance to driver when
backing up and parking. Park Assist
uses ultrasonic sensors in the
bumpers to measure the distance
between the vehicle and objects. The
system calculates the distance
between vehicle and object via
measuring the time it takes for the
ultrasonic waves to bounce back from the object. Park Assist works only at
speeds up to about 11 Km/h (7 mph).
An illuminated LED in the parking
assist button indicates that the
system is ready to operate. The
sensors on the bumpers may detect
objects up to 1.8m (6 ft) behind and
1.25m (4 ft) in front of the vehicle
within a zone 25 cm (10 in) high off
the ground and below bumper level.
These detection distances may be
shorter during warmer or humid
weather. Blocked sensors will not
detect objects and can also cause false
detections. Keep the sensors clean of
mud, dirt, snow, ice, and slush; and
clean sensors after a car wash in
freezing temperatures.
{Warning
The Park Assist System is no
substitute for careful and attentive
driving. The Park Assist system
does not detect children,
pedestrians, bicyclists, animals,
or objects located below the
bumper or that are too close or too
far from the vehicle. It is not
(Continued)
Warning (Continued)
available at speeds greater than
11 km/h (7 mph). To prevent injury,
death, or vehicle damage, even with
Park Assist, always check the area
around the vehicle and check all
mirrors before moving forward or
backing.
How the System Works
The instrument cluster may have a
Park Assist display with bars that
show“distance to object,” driving
direction, and object location
information for the Park Assist
system. As the object gets closer, more
bars light up and the bars change
color from yellow to amber to red.

280 DRIVING AND OPERATING
When an object is very close to the
vehicle rear (<0.6m (2 ft)), five beeps
will sound from the rear followed by a
continuous beep from the rear,
or both sides of the Safety Alert Seat
will pulse five times. When an object
is very close to the vehicle front
(<0.3m (1 ft)), a continuous beep will
sound from the front, or both sides of
the Safety Alert Seat will pulse five
times. Beeps for FPA are higher
pitched than for RPA.
When the System Does Not Seem to
Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARKING ASSIST :If this
message occurs, check the following
conditions:
.The sensors are not clean. Keep the
vehicle's rear bumper free of mud,
dirt, snow, ice, and slush. For
cleaning instructions, see Exterior
Care 0370.
.The Park Assist sensors are covered
by frost or ice. Frost or ice can form
around and behind the sensors and
may not always be seen; this can
occur after washing the vehicle in cold weather. The message may not
clear until the frost or ice has
melted.
If the above conditions do not exist,
take the vehicle to your dealer to
repair the system.
PARK ASSIST OFF : If the PA system
does not activate due to a temporary
condition, the message displays on the
DIC. This can occur under the
following conditions:
.The driver has disabled the system.
.An object was hanging out of the
trunk during the last drive cycle.
Once the object is removed, RPA
will return to normal operation.
.The bumper is damaged. Take the
vehicle to your dealer to repair the
system.
.Other conditions, such as vibrations
from a jackhammer or the
compression of air brakes on a very
large truck, are affecting system
performance. Backing Warning and Reverse
Automatic Braking
Vehicles with Adaptive Cruise Control
(ACC) have the Backing Warning
System and Reverse Automatic
Braking (RAB) system. The Backing
Warning part of this system can warn
of rear objects when backing up at
speeds greater than 8 km/h (5 mph),
and RAB may automatically brake
hard at speeds between 1–32 km/h
(0.5–20 mph).
The Backing Warning System will
beep once from the rear when an
object is first detected, or pulse twice
on both sides of the Safety Alert Seat.
When the system detects a potential
crash, beeps will be heard from the
rear, or five pulses will be felt on both
sides of the Safety Alert Seat. There
may also be a brief, sharp application
of the brakes.
{Warning
The Backing Warning System only
operates at speeds greater than
8 km/h (5 mph). It does not detect
children, pedestrians, bicyclists,

DRIVING AND OPERATING 281
Warning (Continued)
animals, or objects below the
bumper or that are too close or too
far from the vehicle. In some
situations, such as at higher
backing speeds, there may not be
enough time for the short, sharp
application of the vehicle brake
system to occur. To prevent injury,
death, or vehicle damage, even with
the Backing Warning System,
always check the area around the
vehicle and check all mirrors before
backing.
When the vehicle is in R (Reverse) and
the system detects the vehicle is
backing too fast to avoid a crash with
a detected object behind your vehicle
in your path, it may automatically
brake hard to a stop to help avoid or
reduce the harm caused by a backing
crash.
{Warning
RAB may not avoid many types of
backing crashes. Do not wait for the
automatic braking to apply. This
system is not designed to replace
driver braking and only works in
R (Reverse) when an object is
detected directly behind the vehicle.
It may not brake or stop in time to
avoid a crash. It will not brake for
objects when the vehicle is moving
at very low speeds. It does not
detect children, pedestrians,
bicyclists, animals, or objects below
the bumper or that are too close or
too far from the vehicle. To prevent
injury, death, or vehicle damage,
even with RAB, always check the
area around the vehicle before and
while backing.
If the brake pedal is not pressed soon
after the stop, the Electric Parking
Brake (EPB) may be set. When it is
safe, press the accelerator pedal firmly
at any time to override RAB.
{Warning
There may be instances where
unexpected or undesired automatic
braking occurs. If this happens,
either press the brake pedal or
firmly press the accelerator pedal to
release the brakes from the RAB
system. Before releasing the brakes,
check the RVC and check the area
around the vehicle to make sure it
is safe to proceed.
Rear Cross Traffic Alert (RCTA)
If equipped, RCTA displays a red
warning triangle with a left or right
pointing arrow to warn of traffic
coming from the left or right. This
system detects objects coming from
up to 20 m (65 ft) from the left or
right side of the vehicle. When an
object is detected, either three beeps
sound from the left or right or three
Safety Alert Seat pulses occur on the
left or right side, depending on the
direction of the detected vehicle.
